An actuator is a mechanism for opening and closing valves. The advantage of the actuator is that it can close and open automatically without human contact. If the machine is manual, one must adjust the valve with a directional or direct mechanism. If a control problem occurs, the actuator is operated with power, hydraulic pressure, and electricity. One of the actuators that can close and open the valve is a valve for the globe valve. In addition, actuator control can be done remotely. The types of actuators that are widely used are pneumatic, hydraulic, and diaphragm and spring actuators. Aside from that, if you have damaged superior ball screw repair for machines that require linear actuators, we suggest you repair them instead of throwing them away.
Here are 3 common types of actuators:
1. Pneumatic Piston Actuator
Pneumatic piston actuators can work by converting the energy created by compressed air into mechanical motion. Simply put is a drive that is driven by an aircraft. When air is applied, the motion adapts to its type, whether it is linear or rotating.
This actuator contains a piston which helps generate motive power from the air. Basically, this keeps the air high so that it can force the diaphragm to rotate or move the valve stem.
The advantage of pneumatic piston actuators is their simple construction, high capacity, and low torque. It can be operated at high temperatures. High rigidity and very fast beat.
2. Electric Motor Actuators
From the name, it is clear that this actuator uses an electric motor into mechanical torque. So obviously electricity is needed to move it.
The advantage of this actuator is that it has a tight design and very high rigidity. Therefore, there is no pipeline for the pressure supply that needs to be installed. Aside from that, it has a high capacity for problems.
Unfortunately, he has a weakness that is expensive.
3. Electro-Hydraulic Actuators
The principle of this actuator uses Pascal’s law. This implies that the increase in pressure at a certain part of the fluid restriction causes the same increase in pressure in a container. This means that the whole system works when Pascal’s law is applied.
For-profit, this actuator has high rigidity and has high rigidity and output power.
